Why are the seeds of this species difficult? The seeds may have physiological dormancy, which can be overcome by mimicking the seasonal patterns of the species' native habitat.
This species is likely to have Orthodox seeds - dry to 15-20% eRH and store at -20ºC, or as cool as possible.
Germinate on agar, germination paper or sand at a suitable temperature (depending on local climatic conditions).
The seeds of this species may be Physiologically Dormant (based on other species in the same genus and inferred from available information on germination and of characteristics of seeds in this family). If germination is low, overcome dormancy by mimicking the seasonal patterns of the species' native habitat. Use a moist pre-chill or pre-heat treatment (depending on local climatic conditions) or a dry after-ripening treatment, before germinating the seeds on agar, germination paper or sand at their optimum temperature. If this does not work, you can perform delicate surgery to enable the embryo to grow. Excise the tissue near the root tip.
The fruit (2.5 cm x 3-4 cm) is a drupe, ovoid to oblong in shape. Thr fruits are golden yellow in colour and have a thin, tough skin. The pulp is juicy and fibrous. The flesh clings to the white fibrous stone.
